ENE-FARM, a residential fuel cell, began general sales in 2009, and as of the end of September 2020, cumulative sales have reached 372,074 units. Stationary fuel cells are cogeneration systems that generate electricity and heat at the same time, with a total energy efficiency of over 80%. For this reason, it is becoming widespread as an energy device that contributes to CO2 reduction in the prevention of global warming. Ensuring safety is always a top priority. Reviewing regulations such as the Electricity Business Act and Fire Service Act and establishing a third-party certification system are the two wheels of a car to ensure the safety of residential fuel cell power generation systems. All ENE-FARM have obtained the certification mark. This paper focuses on this certification system and introduces the background to the establishment of the certification system and the outline of common certification criteria.
